Great post, i usually use 301 for most of my website and canonical in rare cases. But this is the first time i come across alternate link tag. As i am dealing with a Multilingual SEO sites, this will help a lot i hope.
Thanks for this. January 12, 2011

Example which you have given is so great richard. I think all the designers have to see this post. Because this explains about the navigational structure, design and the technique where they have to learn. July 26, 2010

Hi Rob, This is my first comment on SEOMoz. I have read a lot of new ideas on link building. But i remember that i have tried explaining some of this technique in my present company sometimes back. But the thing is i am not able to explain them in a proper way and my suggestion fails. But now i am able to explain in brief. Let me get pass this time :) July 26, 2010
